To all whom it may concern:

Beitknown'that I, WILLIAM H. TATMAN, a citizen of the United States, residing at. Wann, in the county of Nowata and State of Oklaho'ma, hav e invented new and useternal-Combustion Engines, of which the following is a specification.

The invention relates to engines, and more internal combustion engines.

The primary object of the invention 1s the provision of a device in which an explosive mixture may be admitted thereto for efiecting a high degree of heat on the exploding thereof, thus permitting ordinary kerosene to; be utilized for the running ofinoperationw I Anotherg Dbl Mimi "the nvention is the running ofan emay' beaccomplished with a cheap fuefithereby the bility of damaging said engine, or af't'e'actingv the efiicienoy thereoi, I V A further object of the invention is the which is simple in construction, that"may be applied to any of the. ordinary wellknowntypes of internal combustion engine, thread and that is vthoroughlyreliable and eflicient in operation, and inexpensive in, manu- .facture.

. With these-andother objects-in view, the. invention consists in the; construction, combination and arrangement of parts, as willpointed out in the claimhereunto a pended. ,Jnahedrawmgs; Figure -1 is a agmen-' tion engine, showing the attachment a lid thereto; Fig. is a, vertical .1 itii inal :ig. 3 is Similarrefei'ence characters indicatecor parts throughout: the .seml

'. Referring" to the drawings by numerals,

the essential parts ,thereof, including the casing and connected with a crank 8 on the;

latter being provided with an operating rod 11, by which it is lifted, and is normally heldto its seat in .any ordinary well-known manner, the piston 6 being provided with the ordinary packing rings 12 which frictionally engage the inner wall of the cusing, as usual. i The gaseous fuel for Working the engine is supplied by a pipe 13 runnin from a car bureter (not shown); The exhaust of the burned gases escapes through the exhaust port normally closed by the valve 10, when it is lifted open, and (not shown) as usual. The fuel used for running the engine is theprdinary kerosene, and is fed into the engine cyhnder through the carbureter in a like manner as if 'gasolene were used for fuel. It is a well-known fact that kerosene W1ll not explode until after it has been raised .to a very high temperature, but it does not do'so then with very much force on account. Jf'the slowness of the explosion. Therefore, it isnecessary to efiect arapid explosion and a ,which is accom .presentlydescri ed.

Provided in the head of the cylinder is a spark pl receivg aperture 1 1' in which is detacha roviding an auxiliary combustion chamr 17, in; direct communication with the combustion chamber in the casing 5 of the engine, and into whichis' adapted to be a'srnall quantity of gasolene, the said body 16,. at its top. wall, being vided with an a. erture 18, in which is threaded the ordinary well-known s ark plug'19, while formed in and at one si e of the body is an inlet vent 21, the latter com-' municating with the interior of the auxiliary chamber 17 through a trolled by a spring-he d valve 23 which is automatically operated, ..the vent 21 being ,connected to a tube 24 leadin from a secondary'carbureter (not shown which feeds a gasolene ,fuel mixture to. the auxiliary combustion chamber 17, so that when the piston 'Yfmoyesmutwardly a charge of kerosene .and air will be-taken into themain combustion chamber; in the casing" 5, and also a charge of "gasol'ene and' air will be. taken and upon the return orinstroke of the said piston gs-it compresses the. charges, and at 1y threaded the externally, ed nippel.15'of ahollow body 16,

pro-

ort 22 which is con- Y 1 nto the. auxiliary combustion chamherJlZ J10 the proper interval the electric current through the spark plug explodes'the charge of mixture in the auxiliary combustion chamber 17. This charge, when it explodes,

' enters the maincombustion chamber in the casing 5, and owing'to the great heat, at once explodes the charge of kerosene and air therein, for reversing the piston, and thus effects the running. of the engine.

Of course, it is understood that the attachmentmay be applied at any other desirable point of the englne casing and connection therewith of any other form of carbureter which will be best adapted for the purpose and efficiency of the engine.

' By regulating the valve 23, the intake of air and gasoleneinto the auxiliary combustion chamber 17 may be increased or decreased, as may be desired. Thus, it Will be seen that the ordinary kerosene may be used for fuel with the assistance of a small quantity of gasolene now used for fuel'in engines.

Copies of this patent may be obtained for five cents each, by addressing Washington, 2. G.

vbody and separated from said auxiliary chamber, a valve in said vent and opening into the reduced portion of said chamber for supplying a combustible mixture thereto, and a spark plug mounted hi the reduced portion of said chamber and in alinementwith said valve for exploding said -combustihle mixture Within the auxiliary chamber. In testimony whereof I aitix my signature in presence of two witnesses.
